DOVER — An investigation by the Attorney General's Drug Task Force led to the arrest of a man authorities say was distributing MDMA, commonly known as ecstasy, methylone, and marijuana.

Matthew Coulombe, 24, of Sixth Street also had ketamine and the psychedelic drug DMT in his possession at the time of the arrest. Ketamine is a cat tranquilizer that is popularly used in dance clubs.

A Strafford County Superior Court grand jury indicted Coulombe on Sept. 19. He faces charges that include three counts of a sale of a controlled drug, three counts of possession of a controlled drug with an intent to sell and two counts of possession of a controlled drug.

Lt. Brant Dolleman of the Dover Police Department could not comment on the nature of the undercover investigation, but did say that MDMA, the drug that recently killed a UNH student at a festival in New York City, is in the Dover area.

“MDMA has gotten a lot of attention lately,” Dolleman said, “Certainly it is available in New Hampshire and certainly it is available in this area.”

He added that Dover Police Department takes this matter very seriously. Residents should report drug distribution to the police department so they can handle the matter promptly.
